Best multi FX for the money.

BadBasic 22.09.2023

After trying out alot of other pedals and multi FX pedals in stores and from my friends, I settled for this one. As an amateur bassist in a hobby band, it has everything I need, and then some.
Build quality looks sturdy for a plastic unit, all the buttons feel great and the layout is very intuitive. You have all the input and output connectors you may need, effects are all good at worst, awesome in some instances. 6 impulse responses are very useful and cover a wide range if sounds. Tons of presets, perhaps even too many.
A bit of a learning curve, which is understandable with the amount of features crammed in, but just about everything is footswitch operated. Good as a practice tool as well, with all the drum patterns and a built in looper.

Great product for the price!

Damians9 18.12.2023

For the price, it is a very nice box! Very easy to use, even without reading the manual. Fun to use with quite a lot of effects on board. All necessary I/O, including usb-c.

Perfect for my use case between living room playing and taking it around in a backpack.

Lightweight and easy to use. Many features, very good amplifiers and good quality of the DI. I recommend it for touring. Best choice for professional results in a small package.
